Create Order: Unable to reserve inventory

Hi there!

I’m developing an app in Shopify, and I’m trying to create an order in one store that has installed my app,

this is the request:

{ "method": "post", "url": "[https://xxxx.myshopify.com/admin/api/2020-04/orders.json](http://none)", "headers": { "Content-Type": "application/json", "X-Shopify-Access-Token": "shpat_xxxx" } }

with this body:

{
  "order": {
    "name": "319816",
    "order_number": "319816",
    "tags": "LazadaPH",
    "billing_address": {
      "address1": "St g",
      "city": "Malaybalay",
      "country": "Philippines",
      "first_name": "Jacque",
      "name": "Jacque",
      "phone": "xxxx"
    },
    "shipping_address": {
      "address1": "St",
      "city": "Malaybalay",
      "country": "Philippines",
      "first_name": "Jacque",
      "name": "Jacque",
      "phone": "xxxx"
    },
    "customer": {
      "first_name": "Jaki"
    },
    "financial_status": "paid",
    "location_id": "31103189075",
    "payment_gateway_names": [
      "Lazada_GENERIC"
    ],
    "phone": "xxxx",
    "processing_method": "direct",
    "source_name": "LazadaPH",
    "taxes_included": true,
    "total_price": 850.0,
    "line_items": [
      {
        "price": 850.0,
        "quantity": 1,
        "sku": "RC0010-BX",
        "title": "TheRack",
        "variant_id": "21461967110227",
        "location_id": "31103189075",
        "name": "TheRack"
      }
    ],
    "shipping_lines": [
      {
        "code": "E",
        "price": 148.0,
        "source": "LazadaPH",
        "title": "Entrego"
      }
    ],
    "inventory_behaviour": "decrement_obeying_policy"
  }
}

and this is the response:

{“response_code”:422}

{"errors":{"line_items":["Unable to reserve inventory"]}}

After that response, I consult the inventory level of the item of the order, and the inventory has SKU in that store.
Please, Could you help me in this case? What I should do?
Regards!
